Anti skate question for Rega P8/RB 880 arm

Sounds like they are trying to sell some kind of product, but the bottom line is they are closer to what the tru lift guy is saying versus what Rega is saying. Since seeing a gradation of even 10% on the slider is tough, I'll keep it around .3-.4 or so, in line with what Van den Hul recommends.

Long time ago I had bought a DV 17D2 to go on my RB300 arm, I set AS on the Rega’s slider to match the VTF, 1.95g. After probably a year or two too many I started getting balance issues with the system, I found the stylus was twisted off the vertical and the cantilever was no longer pointing where it should, not bent, it’s a diamond one, but not straight ahead either. My next cartridge, another D2, I set AS using the blank track on “The Enjoyment of Stereo” about half way across the disk, on the slider it was nearer to 1 than 2 this time and the cantilever stayed in line for 5+ years with no CD player to share the burden.

lewm nailed it, and it was a pleasure to read too. About the only thing I might add is the L or R channel distortion people hear is anti-skate being off to a gross degree. Its possible to reach a level where much smaller errors become noticeable. What I noticed only became apparent within the last year or so, center image seemed to tend to be just a bit to the right. Recordings don't always put things dead center so it took me a while to be sure. Well if its off to the right, the right channel is on the right side of the groove, maybe a little too much anti-skate? Adjusted it down very slightly and not only did it shift that little bit more to center but the whole stage became even a little bit more holographic.  

So as with everything analog it seems you get anywhere in the ballpark and its great, but you can always do even a little better than that- but only if you're willing to tweak by ear. Because as lewm so clearly explained these things are all very dynamic and ever-changing, so you have to rely on the one thing able to look at the whole picture, and that is no meter or dial it has to be you.

why do you have a TT? Better than CD?

Certainly not unless the fundamentals are done right.

Most of us (I think I can say), over time have had various turntables, various tonearms, various cartridges, 

It is not rocket science, just the needed tools, and careful patience.

YES Elliott. TT is better than CD or anything digital IMHO. But let’s not go down that road. I had a discussion on a very similar topic a couple months back that went very deep with I think 500 posts. 
This was just what I hoped would be a simple anti skate question which lewm and millercarbon helped answer so it was easily  understandable and didn’t involve buying anything.
